That’s strange, it works for me. At a guess the root of it is that $post doesn’t exist, or that $post->ID is nonexistant.

Can you replace function forumreplylink() { ... } with:

function forumreplylink() {

//must be called from within the loop yadda yadda

global $post;

if( $post ) {

$rl = get_option( 'wpbb_path' ) . '/topic.php?id=';

$tid = felblogtotopicid( $post->ID );

echo '<a href="' . $rl . $tid . '">Reply!</a>' . "n";

} else {

echo 'ouch!';

}

}

If it outputs ouch we’ll know that a missing global $post is indeed the problem. You are using it inside The Loop, aren’t you?
